IME'ROV'EMENT IN CURTAIN ROLLER AND BRACKET.

Speoificationforming part of Letters Patent No. 196,994, dated November13, 1877; application filed June 29, 1877.

To all whom it may concern:

Be it known that I, HERMAN SEEHAUSEN,

. of Memphis, in the county of Shelby and State of Tennessee, haveinvented certain new and useful Improvements in Curtain -Fixtures; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art towhich it appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification, and in which- Figure 1 is aside view of my improved ourtain-fixture. Fig. 2 is a longitudinalsection of the same, and Fig. 3 is an end view thereof.

Corresponding parts in the several figures are denoted by like letters.

This invention relates to a certain improvement in that class ofcurtain-fixtures or rolls in which the accidental unrolling or fallingof the curtain is prevented in the event of the breaking or slackeningof the cord and it consists, primarily, in the construction of the shcave-retaining screw; and, secondarily, of the combination therewith ofits holding or retaining mechanism, substantially as hereinafter morefully set forth.

In the annexed drawing, A refers to an ordinarycurtain-roll, uponone endof which is placed the sheave B, fastened thereto by a screw, 0.

- The screw 0 is made square or angular at c,

and passes through a similarly-shaped aperture in the sheave B, to causethe latter to revolve with the curtain-roll. The screw G is also formedat a point between its angular surface or bearing 0 and disk,hereinafter referred to, with an enlarged annular bearing-surface, 0,upon which is adjusted the sheave holding or retaining mechanism. D is aplate or spring, through which the screw 0 passes, and having radialarms (1 d bearing against the flange of the concaved or dished surfaceof the sheave B. Upon the screw 0 is also inserted, next to the springD, a washer, E, and next to the latter the ratchet F, and between thesaid ratchet and a plate or disk, Gr, formed with the said screw, asecond washer, E. By means of the plate or disk G the ratchet E, withits washers E E, is confined in position against the pressure of thespring D.

Friction is produced by the pressure of the bowed plate or spring D uponthe ratchet F, held between the separating-washersE E, one of which isconfined against the ratchet by the disk or plate G, to hold the ratchetin contact with the detent or stud h, hereinafter more particularlyreferred to.

It will be seen that, when the pressure of the spring D and washers E Eupon the ratchet F is overcome, by drawing downwardly upon the curtainwith sufficient force the roll will rotate independent of the ratchet,and still allow the ratchet to be engaged by its detent or stud h, whichaids in preventing the further rotation of the roll after the release ofthe curtain from the hand.

The washers are preferably made of leather and the ratchet ofsheet-brass, to obtain additional-friction to overcome the weight of thecurtain and at the same time reduce wear, &c.

It will also be seen that the screw 0 can be inserted and withdrawn bysimply grasping and rotating the sheave B in the required direction,thus dispensing with a driver.

H is a bracket, of which there are two to a curtain-roll, and whichreceives the projecting portion or axis of the screw 0. Cast with, orotherwise attached to, said bracket at a suitable point is a projectionor stud, h, to engage the ratchet F, and prevent the rotation of thecurtain-roll only when the cord is drawn.

It is obvious that the friction mechanism can be placed upon the otherend of the curtain-roll instead of upon the end having the sheave overwhich the cord passes, and the same end be attained.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. The screw 0, having an angular bearing, 0, internally to thecylindrical bearing'c', to receive the sheave B having a similar-shapedaperture, by which said screw can be driven into its roll, and thefriction or retaining mechanism can be placed upon and removed from saidscrew.

2. The screw 0, having a disk, G, cylindrical or annular portion orbearing 0', and angular portion 0, in combination with a sheave,ratchet, and washers of a curtain-fixture, substantially as and for thepurpose set forth.

3. In combination with devices for rolling and detaining the curtain,the screw 0, having a disk, G, annular bearing 0, and angular portion 0,internally of its bearing, and all in one piece, substantially as andfor the purpose set forth.

4. The screw 0, having the annular shoulder c, angular portion a, anddisk G in combination with the sheave B, spring l), and washers orplates E F E, substantially as and for the purpose specified.
